Self-Combustion in Fish Meal – A Burning Concern

Fish meal, a vital ingredient in animal feed, faces a unique challenge that extends beyond its nutritional role – the risk of self-combustion. This phenomenon arises from the spontaneous oxidation of fats and oils present in fish meal, leading to a release of heat that, if unchecked, can result in fires.

A. Self-combustion:?

1. Oxidation reaction: Fats and oils in fish meal contain unsaturated fatty acids that are susceptible to oxidation. When exposed to oxygen in the air, the unsaturated fats can undergo oxidation reactions, releasing heat as a by-product.
2. Heat generation: As oxidation progresses, the chemical reactions release heat energy. If the rate of heat generation exceeds the rate of heat dissipation, the temperature of the fish meal can rise, leading to self-combustion/heating.
3. Factors affecting self-combustion: Several factors influence the self-combustion potential of a fish meal including its moisture content, oil / fat content, storage conditions (humidity, temperature), particle size, and the presence of antioxidants.

B. Economic impact:?

1. Financial losses: Incidents of self-combustion can result in significant financial setbacks. The destruction of fish meal batches, storage facilities, and potential legal liabilities can strain the financial health of the businesses.
2. Operational disruptions: Fire caused by self-combustion can disrupt regular operations. The halt in production, delay in the supply chain, and need for emergency responses can contribute to operational inefficiencies.???

C. Preventive measures:?

1. Optimal storage conditions: Storing fish meals in well-ventilated, cool, and dry conditions minimizes the risk of self-combustion. Monitoring and controlling humidity levels are critical factors in preventing the activation of oxidation reactions.
2. Antioxidant utilization: Incorporating antioxidants into the fish meal serves as a preventive measure against self-combustion. Antioxidants counteract the oxidation process, mitigating the release of heat and reducing the risk of fires.
